MIXING DEVICE FOR EXPLOSIVE-ENGINES.

Application filed July 23,

To all whom it may concern Be it known that I, JOHN H. FRITZ, a citizenof the United States, residing at Kansas City, in the county of Jacksonand State of Missouri, have invented a certain new and usefulImprovement in Mixing Devices for Explosive-Engines, of which thefollowing is a specification,

llly'ifivent'ion relates to improvements in mixing devices for explosiveengines.

It relates particularly to novel means for mixing an explosive chargejust prior to its admission to the explosion chamber.

The object of my invention is to provide novel means for obtaininga-thorough intermingling of the constituents of an explosive charge justas it enters the engine cylinder, thus increasing the efiiciency of thecharge, effecting a savin in fuel, and reducing the de osition of caron.

y invention provides further a novel fuel mixing device which is simplein construction, cheap to manufacture, durable and not liable to get outof order, and which can be readily applied to engines'now in use.

The novel'features of my invention are hereinafter fully described andclaimed.

In the accompanying drawing, which illustrates the preferred embodimentof my invention,

Figure 1 is a central sectional view of my improved mixing device shownapplied to an engine cylinder.

Fig. 2 is an outside end view of themixing device.

Fig. 3 is an inside end view of the same.

Fig. 4 is a view, partly in horizontal section and partly in plan, of myimproved mixing devices shown applied to the cylinder and intakemanifold of an engine.

Figs. 5, 6 and 7 are plan views of the three screens respectively.

Figs. 8 and 9 are plan and cross sectional views respectively of amodified form of my invention.

Similar reference characters designate similar parts in the differentviews.

Referring particularly to Figs. 1, 2 and 3, 1 designates a cylinder ofan explosive engine, 2, the intake port thereof, and 3 a fuelconductorwhich leads from the carburetor, not shown, and discharges into the port2.

My invention aims to thoroughl mix the ingredients of the charge just.as t e charge Specification of Letters Patent. 7

Patented Oct. 25, 192i 1920. serial no. 398,353.

of the cylinder 1, and which, preferably, I

has an annular shoulder or flange 9 fitted in the port 2. The dischargeend of the fuel conductor 3 bears' against the outer side of the member8, which serves as a gasket, and which may be substituted for the gasketordinarily used at this place.

For tightly clamping the screens 4, 5 and 6 in the recess 7, I provide aperforate member 10, preferably cup shaped, and which at its inner edgebears against the outer screen 5 adjacent to the periphery of thelatter. The member 10 may have a central longitudinal tubular extension11 which at its inner end bears against the central portion of the outerscreen 5. Extending through the tubular portion 10 is a screw 12, whichalso extends through a transverse bridge portion 13 with which thegasket member 8 is provided. A nut 14 is mounted on the inner end of thescrew 12 and bears against the inner side of the bridge portion 13.

When a charge is drawn into the cylinder 2 from the conductor 3, thecharge passes through the clamping member 10, thence throu h the screens5, 4 and 6 and thence into t e c linder through the member 8 and port 2.n passing through the fine screen 4, the constituents of the charge arethoroughly intermingled, just prior to their entering the cylinder,thereby rendering the combustion more perfect, thus increasin theefiiciency of the charge, the power of the engine and effecting a savingin fuel and the reduction in the amount of carbon deposited in thecylinder.

The coarse screens 5 and 6 serve to support or brace the fine wirescreen 4 and prevents ru ture of the latter from the pressure of t egas.

When the mixing devices are to be used in'connection with an enginehaving a plurality of cylinders and an intake manifold connected withsaid cylinders, the devices are arranged as shown in Fig. 4. In thisfigure, 15 designates the intake ports in the body 16, of the engine,and 17 designates the usual intake manifold. f"

Two asket members 8, carrying the screens f, 5 and 6, and the clampingmembers 10, as shown in Fig. 1, are inserted respectively between thedischarge ends of the manifold 17 and the engine body 16 and in theports 15 respectively.

In the form of my invention shown in Figs. 8 and 9, the three screens 4,5 and 6 are superposed one on the other, the fine screen 4 being theintermediate screen and the three screens extending across a tubularmember 18, which intermediate of its ends is provided with .an annularperipheral hollow flange 19 within which the edges of the three screensare mounted and held clamped together. In applying this form of myinvention to an engine, the ends of the tubular member 18 are insertedrespectively in the port 2 of the engine and in the fuel .conductor 3,the discharge end of the'latter bearing against the annular hollowflange 19, which in turn has its inner side bearing same as has beendescribed with reference to the other form.

I do not limit my invention to the structures shown and described, asmany modifications, within the scope of the appended claims, may be madewithout departing from the spirit of. my. invent-ion.

What I claim is In a mixing device for explosive engines, a ring memberhaving a bridge portion, three screens superposed one on the other,extending across said ring member, the intermediate screen beingrelatively fine, and the other screens being relatively coarse, aperforated clamping member bearing against the center and edges of thescreens, and a securing device connecting the clamping member and saidbridge portion, substantially as set forth.

In testimony whereof I have signed my name to this specification.

- JOHN H. FRITZ.
